What can i say!
I cannot even begin to say how thankfull i am of all the replies on this post, i am touched by all your support and kind words, i now feel so much better about the whole situation.
Looking back, he has for a while been, felling very tired all the time, had cravings for chocolate (but i think he is just addicted

) going to the toilet a lot. His aunt had it, and i believe his nan also had it, so to be honest i was half expecting it, but i was still a bit worried when i found out, especially because i know he hates hospitals and going to the Dr's (Long story!).
At the moment he is still in hospital and i dont think they will let him out until his suger levels return to normal, and understands how his diet will have to change. He was lucky that he didn't break something in his fall really, it was quite nasty, falling head first down a set of very steep stairs. He's just got a lot of bumps on his head and a bad back, not bad for a 18-19 stone, 61 year old!
